Automatic system for evaporation of condensates

ABSTRACT

Consists of the installation of a set of condensation control elements on to the lower rear part of the external condenser units of air-conditioning systems, permitting the elimination by evaporation of the liquid formed in the air-conditioning process. 
     The system is made up of an electric liquid level sensor, which is connected to the liquid collection container on the bottom of the external condenser unit, and which, depending on the level of liquid in the container, activates the pump, which pumps the water through pipes connected to the rear ventilation grille and releases it on to the condenser through atomizers at the end of the pipes, causing the liquid to evaporate, thereby making it unnecessary to install condensed liquid drainage pipes and improving heat efficiency by cooling the ventilation grille of the condenser unit.

PURPOSE OF THE INVENTION

The Invention Patent to which this Report refers is intended toguarantee the exclusive use and ownership, throughout the country, of anautomatic system of evaporation of the condensed liquid fromair-conditioning and cooling units.

SCOPE OF THE INVENTION

The application of this invention is in the temperature and moistureexchange requirements, especially the evaporation of the liquidcondensed during the air-conditioning process (F25), which arise inevaporators due to condensation.

This invention has two important purposes: firstly, it solves one of themost serious problems of domestic air-conditioning units, namely, thepresent need for complicated systems for the drainage of condensedliquids and, secondly, it significantly increases the heat efficiency ofthe unit and reduces power consumption.

BACKGROUND OF THE INVENTION

Nowadays, air-conditioning is the most complete process of ambient airtreatment, involving the regulation of conditions in terms oftemperature (heating or cooling), moisture and quality (renewal,filtering).

Over the last few years, the installation of air-conditioning units hasbecome an essential requirement to achieve people's wellbeing indomestic, work and leisure environments.

The technique has advanced to such an extent that, nowadays, there aremany low-price, high-performance, easily installed, noise-freeair-conditioning systems on the market, but they all lack optimumsystems for the elimination of the condensed liquids produced by thevarious units of which they are composed.

DESCRIPTION OF THE INVENTION

The invention consists of an adaptation to the external condenser unit,such that by installing the device for collecting the water condensed inthe air-conditioning process, in which a simple electric pump forcondensed liquids, a liquid level sensor and a set of small verticalpipes with atomizers at the end are installed, the condensed water ispumped over the external unit condenser and, thanks to the hightemperature of the latter and the action of the equipment's fan, alongwith moisture exchange, the condensed liquid evaporates into the outsideair, eliminating the need to include drainage pipes and/or containersfor the collection of condensed liquids.

DESCRIPTION OF THE DIAGRAMS

To better understand the scope of this invention, we are going todescribe it using the attached diagrams, which show a preferred designof the same, given as an example but not being the only possibility.

FIG. 1 shows a rear view of an external condenser unit with theinvention installed and

FIG. 2 shows a side view of the same.

We can see that, in the diagrams, (1) represents the external condenserunit of an air-conditioning system, (2) the container for condensedliquids, (3) the liquid level sensor, (4) the pump, (5) the verticalpipes, (6) the atomizers and (7) the ventilation grille.

PREFERENTIAL FORMAT OF THE INVENTION

As you can see in the diagrams, the invention is located on thecondenser unit of an air-conditioning system (1) and consists of aliquid level sensor (3), which detects the presence and level of liquidaccumulated in the condensed liquid collection container (2) and, whenthe liquid in the container reaches a high enough level, activates theelectric pump (4). The latter pumps the condensed liquid through therear vertical pipes (5), attached to the external condenser unitventilation grille, from which it is released through the atomizers (6)in the form of a fine spray.

The water released through the atomizers (6) falls directly on to therear ventilation grille (7) of the condenser unit (1), where it quicklyevaporates due both to the temperature of the condenser and the effectof the internal fan of the condenser, as well as the moisture of theoutside air.

When the level of liquid in the condensed liquid collection container(2) drops, this is detected by the sensor, which turns off the pump andtherefore the atomizers.

As you can see, the invention is as effective as it is simple andoriginal. This set of elements: the sensor, the pump, the pipes and theatomizers are easy to handle and install and inexpensive.

With the invention, installation costs are also significantly reduced,since, as already mentioned, it makes it unnecessary to install drainagepipes, which often disfigure the facades of buildings. Energy costs arealso reduced, since the water released on to the ventilation grille bythe atomizers aids in the elimination of heat and improves the heatefficiency of the installation, as shown in the attached diagrams.

Apart from the basic invention, the patent also includes variations indetail, such that there may be variations in the type of level sensorand pump, the characteristics and quantity of pipes and atomizers, thesize of the different parts of the system and, naturally, the materialused.

1. Automatic condensed liquid evaporation system comprising acombination of elements consisting of a liquid pump, a liquid levelsensor and a set of pipes with atomizers on the end, which are placed onthe external condenser units of air-conditioning systems in such a wayas to collect the condensed liquid which accumulates in the lower trayof the condenser and release it in the form of a fine spray over the topof the ventilation grille of the external condenser unit.
 2. Automaticcondensed liquid evaporation system as claimed in claim 1, comprising anelectric liquid level sensor which activates the pump-also electric-onlywhen it detects the presence of a high enough level of liquid in thetray for the collection of water from the drainage pipes of theevaporating and condensing units of the air-conditioning system.
